Summer Special '26: How research builds on research, with Sonia Cabell, Ph.D.

In this episode of Science of Reading: The Podcast, host Susan Lambert, Ed.D., does something a little different, sharing her own research alongside that of her guest, Sonia Cabell, Ph.D. Together, they trace how Sonia's large-scale Institute of Education Sciences (IES) study directly inspired Susan's dissertation, and what that process reveals about how evidence in literacy education actually gets built. Susan and Sonia also discuss what Sonia's IES study on content-rich literacy instruction found; how Susan's own dissertation research built directly on those findings; what it really means for research to "accumulate" and why it matters for classroom practice.
